PORTABLE FORCE-PUMP.

SPECIFICATION forming part of Letters Patent No. 254,266, dated February 28, 1882, Application filed August 6, 1881. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL BONSER, of Dover, in the county of Sin-afford and State of New Hampshire, have invented a new and useful Improvement in Portable Force-Pumps,

of which the following is a specification.

Figure 1 is a side elevation, partly in section, ofmy improvement. Fig. 2 is a sectional front elevation of the same, taken through the line a: 00, Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to improve the construction of the portable force pumps for which Letters Patent No. 238,333 were issued to me March 1, 1881, in such a manner as to make them more convenient in use and adapt them to be used for various purposes.

The invention consists in the combination, with the wheels and axle, of the platform, the tank having a flange around its bottom, the handle bent to form a foot-and stirrup, and the handle-braces, whereby the pump and the liquid to be thrown by the pump can be readily held and carried; and also in the combination, with the tank and the pump-barrel,'of the semicircular plate having its straight edge flanged, and the wooden strengthening-block, whereby the pump-barrel can be securely supported, as will be hereinafter fully described.

Arepresents the tank, which is made of galvanized iron or other suitable material. The tank A is made with a ring-flange, B, around its bottom, to receive the bolts by which it is secured to the wooden bottom or platform (J. The platform 0 is made of the same shape as the tank A, and is bolted to it, a little in the rear of its center, or otherwise secured to the axle D of the wheels E.

To the forward part of the platform 0 is secured the end of a bar, F, which is bent downward, forward, and upward to form a foot to support the heavier forward part of the tank A, and is then inclined forward and upward to form a tongue or handle for drawing the tank from place to place. The handle F is strengthened by the braces G, the forward ends of which are secured to the forward part of the said handle F, and their rear ends are secured to the tank A. The bent part of the handle F also serves as a stirrup to receive the foot of the operator, so that he can hold the pump steady while working it. In case a third wheel is used and placed beneath the. forward part of'the tank A, the handle-bar F can be led over the said wheel.

H is a semicircular plate placed in the middle part of the tank A, and secured at its curved edge to the middle part of the wall of the said tank A. The plate H is stiffened and strengthened by having its straight edge bent downward or flanged, and by havinga wooden block,

I, fitted and secured to its lower side.

J is the pump-barrel, which is made in sections, and with flanges at the ends of the sections, so that they can be securely bolted together, and the lower section can be securely bolted to the plate Hand block I. The pumpbarrelJ has an air-chamber, K, at its lower end, below the valves, as shown and described in Patent No. 238,333.

With an openingin the side ofthcair-ohamber Kis connected by a coupling, tube, or other connection the end ofa flexible pipe, L, to the other end of which is attached a strainer, M, which rests upon the bottom of the tank and prevents coarse impurities from on ter-in g the pump. The strainer M is secured to the pipe L bya union or other suitable detachable connection, so that the said strainer can be detached and one or more lengths of pipe interposed between it and the pipe L when it is desired to draw the water from a well, cistern, stream, or other reservoir.

With the upper part of the pump-barrel J is connected by a union or other suitable connection the end of the flexible discharge-pipe N, which can be made of any desired length, and with the other end of which is connected a nozzle, 0, or a sprinkler, as the purpose for which the pumpis to be used may require.

P is the valve-rod of the pump, the upper end of which works in'a guide-bearing in a bracket, Q, attached to the standard or frame R. The lower part of the standard R is branched or forked, and has projecting flanges or feet upon the lower ends of its branches, to receive the bolts by means of which the said standard is secured to the plate H and wooden block I. When the pump is used separate from the tank A the lower ends of the branches of the standard B have flanges or feet upon both sides, so that it can be more firmly secured to its support.

To the valve-rod P, at a little distance from its upper end, is secured a cross-head, S, to the ends of which are hinged the lower ends of two connecting bars or rods, T. The upper ends of the connecting-bars T work upon pivots or across-bar, U, formed upon or attached to the end of the lever V. The lever V is pivoted to a post, W, upon which it is secured by a pin or other suitable means. The post W has a shoulder near its forward end to keep the lever V in place, and upon its rear end is formed a tenon provided with a screw-thread to pass through a hole in an arm or lateral projection, X, of the standard R and receive the nut Y, by which it is secured to the said standard. With this construction the post W can be attached to either side of the standard R to form a right-hand or a left-hand pump, as may be desired.

When the pump is to be used separate from i the tank J as a sink-pump or other stationary use, a union, 2, or other connection can be attached to the'lower end of the pump-barrelA, as shown in Figs. 1 and 2.

The cover is made in three parts, a b c, the part a of which is attached to the top of the tank A, and has notches formed in it to receive the branches of the standard R and the pumpbarrel J. The second part, b, has a slot formed in it to receive the pump-barrel and allow the edgeofthesaidpart torestagainst thebranches of the standard R.

The parts a b are secured to the tank A by bolts or other suitable means, and assist in strengthening the said pumpbarrel and standard in place. The third part, c, is made with a flange along its curved edge, and is removable to give access to the tank for putting in water and cleaning out the tank. The water is drawn out of the tank through a short pipe or faucet, 61, secured in a hole in the bottom of the tank A, or in the side of the said tank, close to its bottom.

Having thus fully described my invention, I claim as new, and desire to secure by Letters Patent- 1. In a portable force-pump, the combination, with the wheels and axle E D, of the platform 0, the tank A,having a flange, B, around its bottom, the handle F, bent to form a foot and stirrup, and the handle-braces G, substantially as herein shown and described, whereby the pump and the liquid to be thrown by the pump can be readily held and carried, as set forth.

2. Ina portable force-pump, the combination, with the tank A and the pump-barrel J, of the semicircular plate H, having its straight edge flanged, and the wooden strengthening-block I, substantially as herein shown and described, whereby the pump-barrel can be securely supported, as set forth.
